Grammar Rules 动词不定式作宾语 在英语中我们把“to+动词原形”的结构称为动词不定式，动词不定式没有人称和数的变化，在句中可以作宾语。 e.g. I wanted to see the Beijing opera, so Li Ling offered to take me there. 我想看京剧，所以李玲就提出带我去看。 We only planned to watch for an hour. 我们原先只打算看一个小时。 I hope to understand more next time.我希望下次能懂得多一些。 常见的接不定式作宾语的动词 1）希望类：want（想要）, hope（希望）, wish（愿望） e.g. I want to learn English well. She hopes to visit Paris. 2）决定类：decide（决定）, plan（计划）, choose（选择） e.g. They decided to leave early. He plans to study medicine 3）同意/拒绝：agree（同意）, refuse（拒绝） e.g. We agreed to help him. She refused to answer the question. 4）其他常见动词：need（需要）, promise（承诺）, learn（学习） e.g. You need to practice more. He promised to come on time. 动名词作宾语 动名词是动词加 -ing 的形式（如 reading, playing），某些动词后必须用动名词作宾语。 e.g. She enjoys learning about different cultures and traditions from around the world.她喜欢了解世界各地不同的文化和传统。 He practises playing the guitar for two hours every day. 他每天练习两个小时吉他。 常见的接动名词作宾语的动词 1）爱好/厌恶类：enjoy（享受）, like/love（喜欢）, hate（讨厌） e.g. She enjoys singing. I hate waking up early. 2）完成/继续：finish（完成）, keep（继续）, practice（练习） e.g. He finished doing his homework. Keep trying! 3）建议/考虑：suggest（建议）, consider（考虑）, mind（介意） e.g. They suggested going hiking. Do you mind opening the window? 4）其他常见动词：avoid（避免）, admit（承认）, miss（错过） e.g. Avoid eating too much junk food. She admitted breaking the vase. 接不定式或动名词作宾语的动词 需要注意的是，还有一些动词，既可以用不定式又可以用动名词作宾语，但表达的意义可能不同。 1) remember/forget remember/forget to do（记得/忘记要做某事，未做） e.g. Remember to turn off the lights when you leave the room. remember doing（记得做过某事，已做） e.g. I remember seeing him before. 2) stop stop to do（停下来去做另一件事） e.g. He stopped to talk to me. stop doing（停止正在做的事） e.g. Stop talking, please! 3) try try to do（努力做某事） e.g. I tried to solve the problem. try doing（尝试做某事） e.g. Try using this method. 一般来说，用不定式作宾语时，所表示的多为将来的行为。用动名词作宾语时，所表示的多为正在做的行为。 Complete the paragraph with the correct form of the words in brackets.
